Subject: [PATCH 3.14 022/158] ALSA: hda/realtek - Restore default value for ALC283
3.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kailang Yang <kailang@...ltek.com>
commit 6bd55b04fe05cb26094b0fe494c7a207e6c0c36e upstream.
Restore the registers to prevent the abnormal digital power supply
rising ratio/sequence to the codec and causing the incorrect default
codec register restoration during initialization.
